S ummary99m Tc in the pertechnetate form produces little internal radiation and as the mCi dose may be large, a sharp tumor picture with scanning is possible. Comparing this with 203 Hg‐chlormerodrin in phantom and clinical studies, of 47 histologically verified brain tumors, 203 Hg‐chlormerodrin demonstrated 21 out of 39 cases, a 54% diagnosis rate, while 99 m Tc clarified 11 out of 13, or 85%. Local findings in serial angiography were seen in 40 of 47 cases, 85%. Three cases with no angio‐graphic findings gave a positive scan. The extent of some tumors only partially visualized through angiography was determined by scanning.
